Maxxis has partnered with TFB Performance and NASA to determine the vehicle setup that racers should start at when using the new spec tire, the Maxxis RC-1. Maxxis recommends the following vehicle/tire setup while using the RC-1 on the BMW E30 based on data collected from multiple race sessions.
Maxxis Recommendations
Hot Tire Pressure – Target hot tire pressures should be between 33 and 38 psi. Maxxis recommends racers adjust hot pressures at 1-psi increments based on track conditions, tire temperatures, and fine-tune as needed.
Tire Running Temperature – The recommend tire running temperature for the RC-1 is between 140 degrees Fahrenheit and 240 degrees Fahrenheit (60-155 Celsius).
Vehicle Alignment Setup and Test Weight Distribution – Racers should use the following recommendation as a starting setup and adjust to their vehicle, track conditions and driving style.
